Annotation score:4 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

Transcriptional repressor. Binds with MAX to form a sequence-specific DNA-binding protein complex which recognizes the core sequence 5'-CAC[GA]TG-3'. Antagonizes MYC transcriptional activity by competing for MAX and suppresses MYC dependent cell transformation.1 Publication

Miscellaneous

Mice deficient for Mxd3 show increased sensitivity of neuronal and lymphoid cells to gamma-radiation induced apoptosis.

Expressed during neural and epidermal differentiation. Expression restricted to proliferating cells prior to differentiation. Specifically expressed in the S phase of the cell cycle in neuronal progenitor cells. In the developing embryo, detected from 9.5 to 12.5 dpc especially in the ventricular zone of the neuroepithelia, in the progression zone of the limb buds and in the aortic arches and liver. In the spinal cord at embryonic days 10.5, 11.5 and 12.5 dpc, expressed in the cells at the perimeter of the ventricular zone. In the developing epidermis, expressed only in the uppermost differentiated cell layers underneath the stratum corneum.2 Publications
